UBUNTU-CVE-2014-3124
The HVMOPsetmemtype control in Xen 4.1 through 4.4.x allows local guest HVM administrators to cause a denial of service hypervisor crash or possibly execute arbitrary code by leveraging a separate qemu-dm vulnerability to trigger invalid page table translations for unspecified memory page types...

[SECURITY] Fedora 20 Update: qemu-1.6.2-4.fc20
QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation. QEMU has two operating modes: Full system emulation. In this mode, QEMU emulates a full system for example a PC, including a processor and various peripherials. It can be used ...
CVE-2011-1780
The instruction emulation in Xen 3.0.3 allows local SMP guest users to cause a denial of service host crash by replacing the instruction that causes the VM to exit in one thread with a different instruction in a different thread...
Design/Logic Flaw
Xen, when using x86 Intel processors and the VMX virtualization extension is enabled, does not properly handle cpuid instruction emulation when exiting the VM, which allows local guest users to cause a denial of service guest crash via unspecified vectors...

CVE-2011-1780
CVE-2011-1780 affects Xen 3.0.3 and is caused by a flaw in instruction emulation. Local SMP guest users can trigger a denial of service resulting in a host crash by replacing the instruction that causes the VM exit in one thread with a different instruction in another thread. The provided connect...
CVE-2011-1936
CVE-2011-1936 concerns the Xen hypervisor on x86 with VMX enabled. The issue is that cpuid instruction emulation is not properly handled when exiting a virtual machine, which can allow a local guest user to trigger a denial of service (guest crash) via unspecified vectors. The description does no...
Kernel: Xen: Xsa-63: information leak via I/O instruction emulation
Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a 1 port or 2 memory mapped I/O write or 3 other unspecified operations related to addresses without associated memory...
Protection Against Port Scanners: Portspoof
The portspoof program is designed to enhance OS security through emulation of legitimate service signatures on otherwise closed ports. It is meant to be a lightweight, fast, portable and secure addition to the any firewall system or security infrastructure. The general goal of the program is to...
CVE-2013-4551
Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for 1 VMLAUNCH and 2 VMRESUME, which allows local HVM guest users to cause a denial of service host crash via unspecified vectors related to "guest VMX instruction execution."...

Host crash due to guest VMX instruction execution
ISSUE DESCRIPTION Permission checks on the emulation paths intended for guests using nested virtualization for VMLAUNCH and VMRESUME were deferred too much. The hypervisor would try to use internal state which is not set up unless nested virtualization is actually enabled for a guest. IMPACT A...

xen: information leak through outs instruction emulation (XSA-67)
The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information hypervisor stack content via unspecified vectors related to stale...
